A Katy school district student is facing firearms charges after two weapons were found Monday on a high school campus, including one that prompted an evacuation.

The student at Seven Lakes High School was in custody on Monday. His identity has not been released.

The weapon that prompted the evacuation turned out to be a homemade firearm, school officials said. They initially thought it could have been an explosive device and a law enforcement bomb squad was called to the school in the 9200 block of South Fry.

A school staffer was told about a "security threat" - which led to the evacuation - after a regularly scheduled fire drill at 10:05 a.m. that had already sent more than 3,000 students out of the building, officials said.

The suspicious object was in the east section of the sprawling campus.

When the students were moved the second time, they were directed to an area near the campus baseball and football fields.

"We thought it was just another drill. We didn't think much of it," said Sanjana Madakshire, 17, a senior.

Students spent several hours waiting to either return to school or be released.

Madakshire said any information the students received came through word-of-mouth or their smart phones.

"They didn't tell us anything. I don't think they were sure of what to do," she said.

With the campus sealed off, police from several agencies, including FBI bomb squad agents, began sweeping the building and checking the suspicious device.

By 4 p.m., the campus was cleared of any danger. The device turned out to be a kind of firearm known as a zip gun. Such a weapon can be as crude as a pipe with a block of wood for a handle and a rubber band providing the power for a firing pin.

"They are things that are illegal - especially on a school campus," Stanford said.

A rifle also was found in the trunk of the student's car in the school's parking lot, officials said.

Katy ISD officials said the campus will be back to normal on Tuesday although any quizzes and tests scheduled for that day are postponed.
